My IPhone 13 Pro microphone is muffled when using front camera

My front camera mic is muffled whenever I use the camera application built in the phone, but whenever I use third party software like instagram, Facebook, TikTok, and other apps, it is fine. The mic is fine when I’m taking a video using my back camera, but it sounds muffled whenever I use my front camera while recording in the camera app. Please help me fix
